Pre-Cortex ARM CPUs were the same way. Chips did fit crypto engines, matrix multipliers, FFT offload, and color converters there.

- duskwuff 6mo agoSome of them still do. RP2350 has a couple of custom coprocessors, for instance.
- bobmcnamara 6mo agoCool! What do they do? Edit: double precision floating point and fixed latency GPIO at least!
- duskwuff 6mo agoThat's two of them - there's also a "redundancy coprocessor" which implements security features like stack canaries and flow control assertions. (As well as the standard ARM single-precision FPU.)
